Abstract:
Potentiostat-based solutions are widely used as an instrumentation platform for electrochemical and biochemical sensing systems, which are extensively used in areas as diverse as biomedical analysis, food safety and monitoring of environmental pollutants. Biomedical diagnostics is a relatively new application area of these systems, which can allow for in vivo, long-term patient investigation outside of the hospital environment. It is expected that this emerging area will enable physicians to obtain radically new and unique diagnostic information. The development of such an on-chip potentiostat-based sensing system suitable for in vivo biomedical applications is the subject of the present study. The design is realized on a mixed signal silicon breadboard substrate which allows for a low cost and time efficient progression from concept to full integration on CMOS.
